Aug. 8 (Bloomberg) -- Wal-Mart de Mexico SAB fell the most
in more than a month after sales increased less than expected in
July, signaling that Latin America’s largest retailer could be
losing market share.

The stock fell 2.9 percent, erasing this year’s gain, to
37.91 pesos at the close of trading in Mexico City, the steepest
decline since since June 21. The benchmark IPC index decreased
0.5 percent.

Same-store sales rose 1.2 percent in July, the company said
in a statement to the Mexican stock exchange yesterday. That
compares with Grupo Bursatil Mexicano’s 2.1 percent estimate,
analyst Luis Willard said in a phone interview from Mexico City.

“Competitors are being very aggressive when it comes to
pricing,” Willard said. “This has translated into weak
customer traffic for Walmex.”
